Quiet worker to sound tired (4)
I believe the answer is:
pant
'to sound tired' is the definition.
I can't tell whether this defines the answer.
'quiet worker' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano').
'worker' becomes 'ant' (worker is a type of ant).
'p'+'ant'='PANT'
Can you help me to learn more?
(Other definitions for pant that I've seen before include "Struggle for breath" , "Long" , "Breathe noisily after running" , "Gasp for breath (like a hot dog?)" , "Breath rapidly" .)
